    摘要:
    我们已经证明,空气稳定的阳离子金(I)助催化剂具有增强钯催化的交叉偶联效率的能力。具体而言,我们确定1:1 [Pd {P(t -Bu)3 } 2 ] / [Au {P(t- Bu)3 }(NTf 2)]系统相对于[Pd {P(t -Bu)3 } 2 ],在温和条件下进行的Suzuki–Miyaura,Stille和Mizoroki–Heck反应。最近的密度泛函理论(DFT)预测,我们的结果与该化学中主要用作膦清除剂的阳离子金(I)物种相符。

    Differential Effect of 4H-Benzo[d] [1, 3]oxazines on the Proliferation of Breast Cancer Cell Lines
    摘要:
    Background:

    A family of 4H-benzo[d][1,3]oxazines were obtained from a group of N-(2-alkynyl)aryl benzamides precursors via gold(I) catalysed chemoselective 6-exo-dig C-O cyclization.

    Method:

    The precursors and oxazines obtained were studied in breast cancer cell lines MCF-7, CAMA-1, HCC1954 and SKBR-3 with differential biological activity showing various degrees of inhibition with a notable effect for those that had an aryl substituted at C-2 of the molecules. 4H-benzo[d][1,3]oxazines showed an IC50 rating from 0.30 to 157.4 µM in MCF-7, 0.16 to 139 in CAMA-1, 0.09 to 93.08 in SKBR-3, and 0.51 to 157.2 in HCC1954 cells.

    Results:

    We observed that etoposide is similar to benzoxazines while taxol effect is more potent. Four cell lines responded to benzoxazines while SKBR-3 cell line responded to precursors and benzoxazines. Compounds 16, 24, 25 and 26 have the potent effect in cell proliferation inhibition in the 4 cell lines tested and correlated with oxidant activity suggesting a possible mechanism by ROS generation.

    Conclusion:

    These compounds represent possible drug candidates for the treatment of breast cancer. However, further trials are needed to elucidate its full effect on cellular and molecular features of cancer.

  • Competitive Gold-Activation Modes in Terminal Alkynes: An Experimental and Mechanistic Study

    between π‐ and dual σ,π‐gold‐activation modes is revealed in the gold(I)‐catalyzed heterocyclization of 1‐(o‐ethynylaryl)urea. A noticeable effect of various ligands in gold complexes on the choice of these activation modes is described. The cationic [Au(IPr)]+ (IPr=2,6‐bis(diisopropylphenyl)imidazol‐2‐ylidene) complex cleanly promotes the π activation of terminal alkynes, whereas [Au(PtBu3)]+ favors intermediate

    cross-couplings. Specifically, we determined that a 1:1 [PdP(t-Bu)3}2]/[AuP(t-Bu)3}(NTf2)] system provides superior reactivity relative to [PdP(t-Bu)3}2], across Suzuki–Miyaura, Stille, and Mizoroki–Heck reactions performed under mild conditions. Our results are consistent with cationic gold(I) species serving primarily as phosphine scavengers in this chemistry, as recently predicted by density functional
